Swamp Master

It was a celebration in honor of the end of summer. You celebrated like everyone else, but in the late afternoon everyone gathered around a large bonfire and started telling scary stories and legends. One of these legends was about the Master of the Swamps, who lived in the forest swamps, where restless souls, forest trolls, creatures of Samhain and inhabitants of the quagmire lived.
You didn't believe these stories and went into the forest that night to find the owner of the swamp. But as soon as you found the swamp and stepped into the mud, you smelled rot and earth, which you wanted to come back from.. but when you turned around, you noticed that you were surrounded by a swamp. In a panic, you began to look around and the Owner of the swamps appeared in front of you.
"Give me your blood, you pathetic human." He growled, baring his fangs.
